Heat pump repairs in Crawley: what to expect
Whoever installed your heat pump, aftercare can be arranged in Crawley. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Across Crawley and West Sussex, refrigerant repairs on split systems are carried out by an F-gas certified engineer. For repeated faults in Crawley, the engineer looks at the system design as well as the failed part.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Heat pumps installed by another company that need a second opinion
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
What's included
- Reading of error history and operating data
- A clear explanation of the fault and a price for the repair before work goes ahead
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
We repair heat pumps in Crawley whoever installed them, including older monobloc and split systems.
Grants and rules for heat pumps in England
Homes in Crawley can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump repairs in Crawley: questions
Can you work on a heat pump in Crawley that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Crawley, whoever fitted them. Tell us the make and model when you get in touch.
How much does a visit cost in Crawley?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
How often should a heat pump in Crawley be serviced?
Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
